Sex differences in cognition are stable over a 10-year period in adulthood and old age

Sex differences in declarative memory and visuospatial ability are robust in cross-sectional studies. The present longitudinal study examined whether sex differences in cognition were present over a 10-year period, and whether age modified the magnitude of sex differences. Tests assessing episodic and semantic memory, and visuospatial ability were administered to 625 nondemented adults (initially aged 35-80 years), participating in the population-based Betula study at two follow-up occasions. There was stability of sex differences across five age groups and over a 10-year period. Women performed at a higher level than men on episodic recall, face and verbal recognition, and semantic fluency, whereas men performed better than women on a task-assessing, visuospatial ability. Sex differences in cognitive functions are stable over a 10-year period and from 35 to 90 years of age.     

Sex Differences in Cognition are Stable Over a 10-Year Period in Adulthood and Old Age

ABSTRACT

Sex differences in declarative memory and visuospatial ability are robust in cross-sectional studies. The present longitudinal study examined whether sex differences in cognition were present over a 10-year period, and whether age modified the magnitude of sex differences. Tests assessing episodic and semantic memory, and visuospatial ability were administered to 625 nondemented adults (initially aged 35–80 years), participating in the population-based Betula study at two follow-up occasions. There was stability of sex differences across five age groups and over a 10-year period. Women performed at a higher level than men on episodic recall, face and verbal recognition, and semantic fluency, whereas men performed better than women on a task-assessing, visuospatial ability. Sex differences in cognitive functions are stable over a 10-year period and from 35 to 90 years of age.     

Walk the Talk: Financial Fairness in European Club Football

UEFA’s Financial Fair Play (FFP) regulations represent the most restrictive regulatory intervention European club football has ever seen. Put simply, it demands from clubs to operate on the basis of their own football-related incomes. While the policy has attracted considerable attention from the economic and social sciences, very few contributions systematically investigate it from a philosophical-ethical perspective. The present paper fills this research gap by posing questions on FFP in relation to fair play as a normative concept. We draw on sport economic assessments concerning potential outcomes of FFP and argue that the policy should go beyond the mere pragmatic goal of promoting financial sustainability and truly aim for creating a level playing field, otherwise it should not be labeled ‘fair play’.     

老年人记忆补偿的长期稳定性和变异性：来自维多利亚纵向研究的证据

两种记忆状况组来自于参与加拿大维多利亚纵向研究(VLS)的老年人原样本。一种是未受损伤的控制组(NIC), 另一种是轻度记忆损伤组(MMD)。在基线水平和纵向水平上(即5次追踪或12年)比较了他们在日常生活中对记忆补偿技术的使用。我们使用多水平模型(以年龄和教育水平为协变量)来检验基线水平的差异和长期的变化模式。基线的结果表明MMD组被试报告了近期在日常生活中使用记忆补偿策略方面有更大的增长。纵向的结果表明记忆补偿的使用在12年中具有明显的稳定性, 但是与努力相关的补偿机制存在显著组间差异。教育水平这一协变量(可认为是潜在的认知储备指标)和三种记忆补偿策略随时间的不同变化相关。     

Mild memory deficits differentially affect 6-year changes in compensatory strategy use

The authors examined memory compensation techniques used by older adults from 2 memory status groups, not impaired control (NIC) and mild memory deficit (MMD), both at baseline and across a 6-year (3-wave) interval. The groups were derived from a parent sample of 55- to 85-year-old adults from the Victoria Longitudinal Study (NIC baseline, n = 276; memory > parent sample mean; MMD baseline, n = 79; memory > 1 standard deviation below parent sample mean). Multilevel modeling was used to test 3 research questions concerning differences in initial use of, and 6-year changes and variability in, memory compensation. Initial group differences were observed for both a memory compensation technique and a general compensation indicator. Significant differences in 6-year change patterns were observed for 2 memory compensation techniques (recruitment of human memory assistance, investment of extra effort in memory tasks). Interactions of group status and wave showed that older adults with MMD declined in their use of memory compensation strategies, whereas initially NIC older adults increased their use of compensatory techniques over the 6 years.     

Exploring cognitive effects of self reported mild stroke in older adults: selective but robust effects on story memory

Relatively little systematic information is available regarding patterns of cognitive effects of mild stroke in older adults. We explored this problem with a series of two independent samples from the Victoria Longitudinal Study data archives. In Study 1, self-reported mild stroke and neurologically intact matched controls were (a) confirmed as similar on a set of neurocognitive speed, basic cognition, and awareness indicators, and (b) compared for differences on a set of episodic, semantic, and working memory tasks. The mild stroke group was selectively worse on the language intensive story memory task. This effect was partially attributable to a deficit in remembering the most thematic information. Study 2 closely replicated these procedures and results. In addition, Study 2 follow-up analyses, comparing provisional right-hemisphere damaged and left-hemisphere damaged (LHD) participants, revealed that the thematic story memory deficit for mild stroke participants could be due to the selective impairment of LHD participants.     

Health Related Quality of Life and Social Support in Pediatric Patients with Pacemakers

Prior research evaluating health-related quality of life (HRQOL) among pediatric patients with internal cardiac devices has primarily focused on children with cardiac defibrillators, with scant attention devoted to pacemaker recipients. Social support has been conceptualized as a protective factor that partially accounts for differences in HRQOL. This study compares the HRQOL of children with pacemakers with that of healthy children, and examines associations between HRQOL and social support. Twenty-seven pediatric pacemaker recipients completed measures of HRQOL and social support. Their parents also completed measures of child HRQOL. High concordance was found for child and parent-proxy reports of child HRQOL. Children with pacemakers and their parents both reported relatively low child HRQOL when compared to published normative data for healthy children and parents of healthy children. Family and friends emerged as the sources of support positively associated with the greatest number of HRQOL domains. In conclusion, these findings suggest that pediatric pacemaker recipients experience lower levels of HRQOL compared to healthy peers, and that social support from those closest to the child is associated with their perceived HRQOL.
